An MX record is a type of DNS record that directs email to the correct mail server for a domain.
Why it matters:
- Determines where emails sent to your domain (e.g., @yourcompany.com) are delivered.
- Without correct MX records, email won’t reach your inbox.
- Critical when setting up or migrating mail services (like Microsoft 365 or Google Workspace).
Pro tip: Always verify MX records after changes — even small typos can cause major email delivery issues.
